Brief Summary
This study aims to investigate the impact of menopause-related sleep fragmentation on metabolic biomarkers of body fat gain. The investigators hypothesize that experimental sleep fragmentation will result in an adverse leptin response as a metabolic biomarker for body fat gain.

Outcome Measures
Primary Outcomes (1)
Normalized Serum Leptin Levels
12-hr overnight fasted AM (morning) blood samples were assayed for leptin levels on study days 2-6 under both estrogenized and estradiol-withdrawal conditions \[total: 10 samples\]. For each individual, leptin values were normalized relative to the mean baseline leptin value. Baseline was defined as the unfragmented estrogenized condition (avg. of study days 2-3 in the estrogenized condition).
pre/post sleep fragmentation (3 days); pre/post estradiol withdrawal (~5 weeks)
Secondary Outcomes (1)
Normalized Satiety Scores
pre/post sleep fragmentation (3 days); pre/post estradiol withdrawal (~5 weeks)
Study Arms (1)
Study arm
EXPERIMENTALParticipants completed 2 nights of unfragmented sleep followed by 3 nights of experimentally-fragmented sleep during high estradiol (E2) phase of their menstrual cycle (Sleep Block 1). A subset of participants repeated these procedures in an experimentally-induced low-E2 state (Sleep Block 2).
Interventions
one injection of open-label intramuscular dose of leuprolide (3.75-mg depot), a gonadotropin-releasing hormone agonist that rapidly suppresses estradiol and temporarily achieves ovarian suppression.
